the problem with this logic is that the entire reason spock joined starfleet in this timeline is because he already had an attitude. that's also the reason why this spock simultaneously clashed and got along with jim when they first met.

I could just picture a tos episode where they have to do this for some godforsaken reason. Their facial expressions are perfect-- Bones is regretting his entire life, Kirk is just rolling with it, and Spock, of course, feels nothing.
